Seedling Sowing Equipment Designed to Enhance Seedling Survival Rates and Promote of Agricultural Inputs for Better Crop Outcomes

2BP-1200 Automatic Rice Nursery Tray Seeding Machine — Product Overview

The 2BP-1200 is the top-capacity model of our stationary-type automatic rice seeding line series, built for the largest commercial rice nurseries, seedling production bases, and agricultural cooperatives. Designed around a fully integrated conveyor system, the machine completes the entire tray-seeding process — conveying, soil spreading, watering, precision seeding, and covering — in one continuous, automated cycle. With a market-leading hourly output of 1,200 trays or more, it is the definitive solution for high-volume growers who must finish peak-season nursery preparation in the shortest possible time.

Key Features

Fully Automated Workflow: The machine executes the complete five-stage seeding cycle — conveying, soil spreading, watering, seeding, and covering — without manual intervention between stations, ensuring consistent, repeatable quality across every tray at full line speed.

Hopper-Type Soil Delivery: Both the bottom soil spreader and the covering soil device adopt a hopper (bucket-type) design, delivering smooth, controlled soil discharge that remains stable and uniform even at the highest operating speeds.

Dual 50-Liter Soil Boxes: Generous-capacity soil boxes for bed soil and covering soil support extended continuous runs, minimizing refill stops during peak production.

Precision External-Groove-Wheel Seeder with Stepless Adjustment: The seeding unit adopts an external groove-wheel metering mechanism with 2 fixed gears plus stepless variable-speed adjustment, enabling infinitely fine control of seeding density — more precise than fixed-position designs. Seeding rates adapt easily to hybrid rice, conventional rice, different tray specifications, and regional planting requirements. The 32-liter seed box ensures long, uninterrupted operation.

Rotary-Brush Leveling: A rotary brush finishing system gently evens the covering soil layer, producing a smooth, uniform surface that promotes even moisture retention and uniform germination.

Roller-Chain + Conveyor-Roller Transmission: The robust chain-gear and roller drive system delivers smooth, synchronized tray transport with minimal slippage, engineered for continuous heavy-duty operation at maximum throughput.

Compact Fixed Structure: Despite its class-leading capacity, the stationary frame keeps the same well-balanced 866 × 54 × 114 cm footprint as smaller models, installing easily in workshops or nursery houses on stable, vibration-free leg supports.

Electric Drive, Low Running Cost: Powered by a single 370W electric motor, the machine delivers exceptional output-per-watt, runs quietly and cleanly indoors, and requires no fuel.

Functions

Tray Conveying: Automatic infeed and synchronized high-speed transport of nursery trays along the full-length roller conveyor.

Soil Spreading: Uniform distribution of bed soil via the hopper-type spreader to form a consistent seedbed base.

Watering: Controlled moistening of the seedbed to create optimal germination conditions.

Precision Seeding: Metered, evenly distributed seeding via the external groove wheel with 2-gear + stepless adjustment.

Covering & Leveling: Uniform top-soil covering by hopper discharge, followed by rotary-brush leveling for a flat, consistent finish.
